two hurts in one photo. first the shaky scaffolding and then all the debris to impale yourself on when you fall from it. I almost sent a guy home wednesday for putting one end of a 24 foot werner decorator plank on the top of an eight foot step ladder. ON SAND! I said "Ed? WTF's wrong with you? I can't see how you have been a carpenter for over 25 years and haven't crippled yourself, take it down"
ETA, looked at the photo immediately above that shaky scaffold one. I see a tripping hazard with all that hose laying on those wood planks. It was a great idea though to leave that finger gap just above the 2X4 sub facia for the guy to grab onto when the scaffold collapses. And why the board roof sheathing? Don't they have plywood in Tennessee yet?
